There is some info in the readme file about start options for Heroes. At the near end you will find the options for the window.
If you want to use these option you have to start it from a Terminal.
'heroes --full-screen' makes the window do full-screen (not that hard is it)

In the folder there is already a small script to double the size of the original window, if you open it in a window you can change the size from 1 to 4 or even use full-screen in there ...
If you really want a binary for a fullscreen version just drop in a note here and we'll help you out.
